Hi,

I have got a question of swapping two int variables without using any predefined builtin function and without using any temp variable.

if int a=3; int b=2, without using temp variable i have to get the output as a=2 and b=3.

How can i do it?

This should work.

a^=b^=a^=b;

a += b;
b = a - b;
a = a - b;
